Almost thirty years after its introduction, the AppleLine Protocol Converter (1985) remains one of the rarest pieces of commercial hardware Apple has ever produced. It allowed a single Lisa, Mac, or Apple II to communicate with IBM mainframes using the IBM 3270 terminal protocol.

As far as I can tell, this is only the second photo of the AppleLine ever posted on the Internet (the first was in a slideshow from last year — see below). I bought this particular Apple service sheet just to share a photo of this elusive beast with you.

In 1983, Apple released a similar (and similarly rare) product, the Apple Cluster Controller, which I wrote about in this Macworld slideshow from last year. One model of the Cluster Controller allowed up to seven Apple Lisas to connect to an IBM mainframe (again, via IBM 3270), which required an intelligent protocol conversion process. As such, the Cluster Controller contained its own CPU and was a miniature computer unto itself, but technical specifications of either device are hard to track down.

If you or anyone you know owns an Apple Cluster Controller or AppleLine protocol converter, I'd love to hear from you. They are so rare I'm not sure if they even exist anymore. (Perhaps Apple only leased them out and recalled all the units when they phased them out, keeping them largely out of private hands. But this is pure speculation on my part.)

A Macintosh SE sits in the home office of Benj's father, March 20th, 1988

My father bought the Macintosh SE you see in this photo pretty soon after it came out in 1987. It proved to be a key tool in launching his business the following year. His company's logo, sales literature, and product manuals were all designed on it. It was an amazing upgrade over a DOS-based PC.

Naturally, my brother and I immediately started to use the SE to play games. We had access to very few titles, though — we played Shadowgate, Dungeon of Doom, Silent Service, and that's about it. I was always disappointed with the Mac's lack of color, but the sharpness and resolution of its display were hard to beat at the time. And the sound was amazing too. The evil laugh in the beginning of Shadowgate still rings clear in my memory.

The SE pictured in this photo remains in my collection to this day, and I boot it up from time to tinker with it. Perhaps I should fire it up again today in honor of my dad.

Discussion Topic of the Week: Did you ever use a computer in one of your parents' offices? Tell us about it.

Back in the mid-late 1990s, an Internet-based BBS platform called Hotline sprung up and quickly spread throughout the Macintosh community. It was basically a client/server BBS software suite that allowed for multi-user chat, file transfers, and message boards.

By the early 2000s, though, Hotline had mostly died out. Today, only a handful of servers remain. But guess what? You can still connect to them — on Windows or a Mac. A new article I wrote for Macworld, "Hotline Revisted," tells you how.

I last updated you on my Macworld work back in January. Since then, I've been busy writing more historically-minded pieces for the site as well as its sister site, TechHive. Below you'll find a list of the ones I haven't mentioned yet on this blog in convenient digest form.

It's Black History Month once again in the US, so I thought it would be timely to share this Apple PowerBook advertisement from 1992.

The ad appeared in the February issue of Smithsonian Magazine; I don't think it is a coincidence that it prominently featured people of African descent. It also prominently featured the PowerBook 100, which had just been introduced a few months prior in October 1991.

The obvious racial focus of this ad brings to my mind a couple of interesting, if racially-charged questions: What percentage of black Americans, historically, have used Apple products versus other computer brands? Do African Americans, like other demographic groups, have their computer or tech brands of choice?

Today, Apple is such a mainstream company that the answer to the first question is most certainly larger than it likely was in the pre-iPod era. It would be interesting from a cultural standpoint to peek back into private demographic customer studies that Apple no doubt commissioned at various points in its history.

As for an answer to the second question, I have no idea. But I would love to hear from African American computer users to find out.

This week we're taking a look at another image that made the rounds in the BBS days, DRAGON6.GIF. In it, we see two digitally illustrated Chinese dragons who appear to be springing forth from a magical stone. Iridescent waves crash around them, and smoke curls throughout an ethereal void. The color palette is rich and bold, underscoring the image's Eastern art influence.

At the moment, the artist behind this amazing work of digital art remains unknown. Still, we can narrow down when the image was made and how by taking a look at its resolution, color depth, and file date.

Since my last update on the articles I've written for Macworld in November, I've written at least a handful more vintage-related stories for the publication that I haven't mentioned on this blog. To remedy that, I thought I'd share them below in convenient digest form.

Thirty years ago last Saturday (January 19th, 1983), Apple announced two new computers: the Apple Lisa and the Apple IIe.

Ultimately, the Apple Lisa met an early end, leaving behind technology that shaped the entire industry. The Apple IIe remained a reliable breadwinner during uncertain times in the early life of the Macintosh and remained the flagship member of Apple's popular 8-bit computer line until it ended in 1993.

Here's the cover of the March 1983 issue of Popular Computing which featured Apple's two new machines. It has always been one of my favorite vintage computer magazine covers.

Long before Boot Camp and Parallels, if you wanted to run IBM PC compatible software on your Mac, you had to strap on this unholy contraption — the Dayna Communications MacCharlie.

If I recall correctly, the MacCharlie was essentially an IBM PC clone in a beige box that hooked to the Mac's serial port. As a result, the Mac merely served as a serial terminal for the MacCharlie via custom terminal software running on the Mac. That's not a particularly efficient setup, but the lack of expansion ports on the original Macintosh meant that there was no other reasonable point of entry.

Since it worked through the serial port, the MacCharlie could only run text-based MS-DOS applications. Conveniently, the MacCharlie shipped with a keyboard extender that added the IBM PC's special function keys and a numeric keypad to the Macintosh keyboard.

Discussion Topic of the Week: Have you ever used a hardware system adapter (something that lets you use software from one platform on another through hardware, not software emulation) for any computer system?

In honor of the impending New Year, I bring you this ray traced image that dates back to December 1992 — 20 years ago — and celebrates New Year 1993.

As per its inscription, this image was created using StrataVision 3D and retouched with PhotoMac by its author, CT. I have not determined who CT is yet, but I will do some more poking around soon and update this entry if I find out. (If you find out first, please let me know.)
